Question: During gravel loading operations, the wheel loader operator identifies a high bank face that shows signs of instability, such as cracks or sloughing. What is the operator's safest course of action?

Answer options:

• Load quickly from the base of the unstable section to remove the material. ✅ Notify the supervisor immediately and establish a safe perimeter, then suspend operations in that area until assessed by a competent person.
• Use the bucket to push down the loose material from a safe distance.
• Continue loading from an adjacent, stable section of the bank.

Correct answer: Notify the supervisor immediately and establish a safe perimeter, then suspend operations in that area until assessed by a competent person.

Explanation: Any sign of bank instability (e.g., sloughing, cracking) poses a serious hazard of collapse, which can engulf a loader. The operator must stop work, evacuate the hazard area, and immediately report it to a supervisor. A competent person must assess the bank before resuming operations, as per OHS regulations concerning ground stability.
